DYNAMIC TESTS OF FULL-SCALE STRUCTURES.

Basic objectives of dynamic testing are outlined, and major test types are summarized. Force generation equipment suitable for tests of full-scale structures is described, and typical results are given, with examples drawn mainly from the field of earthquake and wind excitations. Results of low-level ambient vibration tests are compared with higher-level vibration generator tests, and with excitations caused by strong earthquake ground motion. Some instrumentation systems suitable for such testing are described. Information is given on the ground motions caused by large underground explosions, and the use of such explosions to simulate damaging earthquake excitations is considered.
